Stars make up the majority of what we see in the night sky. For all practical purposes the universe contains almost an infinite number of stars (billions upon billions .). Stars have been studied for as long as humans looked up at them. They are classified, categorized, and we have seen images of both the beginning and ends of stars. This paper will discuss the nature of the birth to the end-of-life cycles of stars.
The universe is an expanding amalgam of gases, particles, dust, heat, cold and everything that is around us. One Major basis of what we see and measure in science are electromagnetic waves. They make up an emission (either natural or man-made) that depending on the cycle of the wave (how close they are together) resides on a spectrum. At the low end of the septum are radio and micro-wave types of waves. At the higher end are gamma and beta form of waves that are so tight that that cycles are an atoms width or less apart.
Of the entire spectrum only a very small swath makes up what we can see with our eyes. The rest can be measured and seen by various instruments and other devices. Observing stars is not only done by the means of seeing them, but by also observing the waves they put out Xrays, Gamma rays and other waves we do not see with the naked eye.
The American Heritage Dictionary defines the universe as:
"All matter and energy, including Earth, the galaxies and all therein, and the contents of intergalactic space, regarded as a whole. It is known that the universe is expanding rapidly, and that all other galaxies are "rushing" away from us. The universe is made up of many different structures arranged in a fairly well-defined hierarchy"
Stars, which are formed by the compression of gases and other matter from nebulous materials in space are considered the smallest aspect of the hierarchy of the Universe. That is they are super-abundant in nature but from a hierarchal perspective they are the... [continues]
